can taking tramadol 50 mg for 2 nights (then cut to 25 mg for 5 nights) lower your potassium level? My mom, 89 years old, developed hallucinations, a severe anxiety attack, etc. Hospital only found low potassium. Stopped tramadol and started potassium supplements , was normal about a day later. (Her potassium level was 2.4 in hospital, now 4.8.) Thanks.
